The nave is a grammar of forces. Ribs collect vault loads, pointed arches minimize lateral thrust, and bay modules choreograph vision. Repetition builds tempo; structure builds clarity.

📐 Geometry & Loads

Rib convergence: Forces meet at bosses and piers.
Pointed arch: Reduces horizontal thrust, allowing higher vaults.
Bay grid: Predictable repetition that stabilizes sight.

$$ ext{Thrust Angle} = arctanleft(rac{ ext{rise}}{ ext{span}} ight) quad ext{(lower with pointed forms)} $$

Variable	Influence	Outcome
Rise/span	Thrust	Window height potential
Rib count	Load paths	Vault articulation
Pier section	Stability	Slenderness control

👀 Sightlines & Rhythm

Clerestory bands: Establish visual tempo.
Pier alignment: Guides forward attention.
Aisle contrast: Side aisles offer shadowed relief to the bright core.
